Zusammenfassung: | A power module includes: a base plate having a first surface; electrode plate provided at the first surface; a wire connected to a semiconductor chip and the electrode plate; a metal member connected to the electrode plate; a terminal plate; a first resin layer, a connection portion of the wire and the semiconductor chip being disposed inside the first resin layer; and a second resin layer provided on the first resin layer and having a lower elastic modulus than the first resin layer. The terminal plate includes a bonding portion contacting an upper surface of the metal member, a curved portion curved upward from the bonding portion. The curved portion is disposed inside the second resin layer, and a length from the first surface of a lower surface of the bonding portion is greater than a length from the first surface of the connection portion. |
